The problem, IMO, is that conservatives have devolved into a factless lot. There was MA and Issy (not the same ideology but usually opposition to the usual crowd here) and katydid does valiantly put forth her ideas, albeit less frequently than we might like.
Back in the day there were more folks with conservative views but not sure where they all wound up.
Anyway, I don't think echo chamber really fits here because we seem to find enough stuff to bicker amongst ourselves. grin Just as with any human grouping.
We probably just all pretty much agree on Trump being one of the worst things the conservative movement has wrought (as do many conservatives).
